Centennial Planetarium Renovations

The former Centennial Planetarium is designated to provide a public space for arts, culture and heritage purposes.  It was placed on Calgary’s Heritage Inventory in 2009 because of its cultural and historic significance to Calgarians. 


Centennial Planetarium, a City-owned building at 701 11th Street SW, opened in 1967 to mark Canada’s Centennial, ad was occupied until June 20, 2011. The facility had not been upgraded or renovated in many years and was urgently in need of renovation to support future occupancy.

Recreation facilities are a critical component in ensuring active, cultural, vibrant and complete communities. The former planetarium is being renovated to provide a modern, safe space that meets current occupancy requirements and building standards.


The budget for this project, including planning, design and construction, is $24.5 million. Renovations to the facility are funded by the Government of Alberta’s Municipal Sustainability Initiative (MSI). The investment ensures the long-term viability of recreational spaces.


The facility is designed to the Access Design Standards (2016) for accessibility.
